"Permission Denied" in Node on Linux, when running start-script /w local nodemon/mocha/babel-node

I'm having issues with my new linux setup - I've installed nodemon as a local dependency (NOT globally) and I'm trying to execute it from my package.json "start"-script. I'm getting this permission error.
